更新在 Laravel 中有很多关系

Question

我正在Laravel 5.5 中构建一个小型应用程序，其中有两个模型：Interaction 和Interaction Summary 在我的Interaction 模型中我有以下关系：

public function meetingSummaries()
{
    return $this->hasMany('App\InteractionSummary');
}

现在创建我在控制器中使用的交互：

$data = $request->only('user_id', 'event_type', 'schedule', 'summaries', 'type', 'venue', 'with_client');
$data['schedule'] = Carbon::parse($request->schedule)->addHours(5)->addMinutes(30)->toDateTimeString();
$meeting = [];
$meeting['user_id']= $data['user_id'];
$meeting['schedule'] = $data['schedule'];
$meeting['type'] = $data['type'];
$meeting['with_client'] = $data['with_client'];
$meeting['venue'] = $data['venue'];
$meeting['event_type'] = $data['event_type'];
$interaction = Interaction::create($meeting);
if($data['summaries'])
{
    $container = [];
    foreach($data['summaries'] as $summary)
    {
        $summary = (Object)$summary;
        if($summary->client['label'])
        {
            $container[] = new InteractionSummary([
                'company_id' => $summary->client['label'],
                'nature' => $summary->type,
                'user_id' => $summary->mention['label'],
                'action' => $summary->action,
                'feedback' => $summary->comment
            ]);
            }
        }
    }
    $interaction->meetingSummaries()->saveMany($container);
}

但在更新时我不知道如何克服这个问题，因为在我的领域中可能存在新的或旧的关系数据。我正在尝试这样的事情：

if($data['summaries'])
{
    $container = [];
    foreach($data['summaries'] as $summary)
    {
        $summary = (Object)$summary;
        if($summary->id)
        {
            $container[] = new InteractionSummary([
                'id' => $summary->id,
                'company_id' => $summary->client['value'],
                'nature' => $summary->type,
                'user_id' => $summary->mention['value'],
                'action' => $summary->action,
                'feedback' => $summary->comment
            ]);
        }
        else {
            $container[] = new InteractionSummary([
                'company_id' => $summary->client['value'],
                'nature' => $summary->type,
                'user_id' => $summary->mention['value'],
                'action' => $summary->action,
                'feedback' => $summary->comment
            ]);
        }
    }
    $interaction->meetingSummaries()->save($container);
}

这是向我发送错误：

类型错误：传递给 Illuminate\Database\Eloquent\Relations\HasOneOrMany::save() 的参数 1 必须是 Illuminate\Database\Eloquent\Model 的实例，给定数组，在 ~\app\Http\Controllers\ 中调用第 449 行的 InteractionsController.php

如果我这样做：

$interaction->meetingSummaries()->saveMany($container);

我得到重复的新字段。

指导我如何克服这个问题。谢谢。

Answer 1

使用findOrNew() 方法：

$summaryItem = InteractionSummary::findOrNew($summary->id);
$summaryItem->fill([
    'company_id' => $summary->client['value'],
    'nature' => $summary->type,
    'user_id' => $summary->mention['value'],
    'action' => $summary->action,
    'feedback' => $summary->comment
]);
